Laser Blended Vision

Throughout life, the crystalline lens gradually loses its natural elasticity. This elasticity, called accomodation, allows us to alternate between far and near vision. The loss of accommodation (presbyopia) is part of the natural aging process of the eyes and affects everyone over 45.

Why should we settle for “monovision”?

Until very recently, “monovision” was the only option to compensate for the effects of presbyopia by laser surgery. Monovision aims at correcting one eye (dominant) for distance vision and at leaving the other eye slightly under-corrected to provide clear near vision.

However, monovision compromises the quality of vision when using both eyes (binocular vision):

• Each eye sees clearly at only one distance, this creates a gap of blurred vision at intermediate distances.
• The visual perception of depth is affected.
• The blurred vision in one eye can degrade vision at distance and induce perception of halos around lights at night.

A superior alternative

Thanks to the Zeiss MEL-80™ Laser, the IRIS Ophthalmology Clinic offers Laser Blended Vision which increases depth of field in both eyes. This increase in depth of field enables the dominant eye to see from distance to intermediate, while the non-dominant eye sees at near through to intermediate. Thus, an intermediate blend zone is created where both eyes have similar vision. This preserves depth-perception and allows patients to see near, intermediate and far without glasses.

To be a good candidate for this corrective option, you must be willing to accept a slight difference in vision between both eyes.

In addition to that, you may need to use prescription corrective lenses to enhance your vision when you do precision tasks (e. g., reading small prints, needlework).
